Which term is another name for compact bone?

Which term is another name for compact bone?

• A. Cortical bone
• B. Cancellous bone
• C. Trabecular bone
• D. Medullary bone

Answer: (A)

Compact bone is the dense, outer layer of bone that gives strength and rigidity to the bone. The term used for this outer, compact portion is cortical bone, so cortical bone and compact bone are essentially the same structure. This dense layer forms the protective shell around the inner cancellous (spongy) bone and is organized into osteons with concentric lamellae that maximize strength. In contrast, cancellous or trabecular bone is the lighter, porous interior, and the medullary region refers to the marrow-filled cavity inside the bone. So the best answer is cortical bone because it is just another name for the compact, dense outer bone.
